reprogrammed.
CONNECTED MODE FLASHING USING TechCONNECT
NOTE: Capable but not recommended.
In this mode, the DRBIII® remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII® is connected to the TechCONNECT Client
using the GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the
CH7000A for most vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash
updates for the vehicle you are connected to by clicking on the "Read Part Number(s)
From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT
Client while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option
and clicking “Download/Update” button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE: This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT
Client. This is a popular mode for flashing in a remote area of the service garage or in a
back lot.
Before you attempt to use this mode, you must configure the DRBIII® for the desired
update(s). To do this, you must connect the DRBIII® to the TechCONNECT Client using
the GPIB cable and the CH7025 cable. It is not necessary to be connected to a vehicle.
The GPIB (CH7035) cable will be used to communicate with the TechCONNECT Client
(for update file downloading) while the CH7025 cable is used to provide power to the
DRBIII®.
After making the above connections, you are able to select one or more updates that you
want to perform. These selections are made by highlighting the desired updates and then
clicking on the "Download/Update" button by selecting the DRBIII® option on the
TechCONNECT client. Obviously, the DRBIII® does not have unlimited memory. If the file
size of the selected updates exceeds 948 KB, the "DRB Space Used" indicator (at the
bottom-center of the TechCONNECT Client screen) will change color from GREEN to
RED. At this point you must de-select entries until the indicator changes color to GREEN
again.
When the updates have finished downloading, you may disconnect from the
TechCONNECT Client and take the DRBIII® to wherever the vehicle is located. The
updates will remain in DRBIII® memory for 8 hours while the DRBIII® is without power. If
the DRBIII® is powered up for several minutes before the 8 hour time period has expired,
the update files will remain on the DRBIII® for another 8 hours without power.
